This week on Car Talk, Chemistry 101 is in session, as Tom and Ray try to figure out whether Dr. Pepper can substitute for Coca Cola as a battery cleaning solution. Happily, there won't be any hands-on experiments, so the chance of a studio fire is remote. Elsewhere, Mary Lou in DC is wondering why her car smells like it just left the pancake house; Rick in Michigan thinks he's got a coffee grinder under the hood; and Lynn in South Carolina wants to know how to kill the three junkers her husband's making her drive. Also, on Stump the Chumps, did Tom and Ray succeed at getting Ralph's Suburban to stop playing "Beat the Clock"? All that and more, this week on Car Talk.
